Be it known thatI, VITO GLIson, acitizenof Italy, and a residentsof 'lVat-erbury,

county of New Haven, and State of Conmanually operated sprinkler system for use be localized to the particular in dwellingliouses and other buildings.

Oneob ect of this invention 18 to provide a'fire extinguishing system ofthe above nature in which a sprinkler unit is provided 1n each room of the building, and having means for operating said units either individually or collectively. I

A. further object is to providea sprinkler system which may be connected -with the r ordinary water distributing pipes of the city 111L1=11S,' and -whiclr will have aseries' of individually operatedfvalves for separately delivering'water to-the sprinklerunits'in the separate rooms, and a common valve for simultaneously delivering "waterato all of the sprinkler units in'the building.

A further object is toprovide, a sprinkler system in which the-sprinkling action will part of a building where the fire occurs.

Afurther object is to provide-a system of the'above nature-which will be very positive and reliable inwoperation, and which will not depend upon any complicated thermal -operated devices which are likely to be defective andteasily' get out of order.

Acturther object istoprovide an apparatus of thef above'nature which will be sim- )le inex aensive to manufacture eas to a l a install and 'manipulate, and durable in use.

With these and other objects in view, there have'been illustrated on the accompan -ying drawing, one :form in which the invention may be conveniently embodied 1 in. practice. Fig. 1 represents asideview of one of the sprinkler units show-n. partly .in section.

Fig. 2 is a diagrammatic sectional view of and very efiicient 1 a building in which the fire extinguishing system has been-installed.

3Figf 3 is adetailed view of a wing of one of the individually-operated valves for controlling the flow of water to one of the sprinkler units.

Fig. 4 is a view on an enlarged scale of a set of sprinkler valves and operating nozzles.

Referring now to'the drawings inwhi'ch like reference numerals denote corresponding parts throughout the several views,-the numeral 10 indicates a building comprising a basement 11, first floor rooms 12, 13 and 14 and second floor rooms 15, 16 and 17. A supply of water is adapted to be received from the citymains through a pipe 18, and said pipe is connectedto apair of vertical pipes 19 and:20,yas clearly shown in Fig. 2. The pipe 19' serves as a main feed pipe-for operating the sprinkler units, while the pipe 20-comprises an auxiliary pipe for simultaneously operating the individual valves of the system;

In order to controlthefiow of water in the auxiliary pipe 20, provision is made ofa valve 21' located in any convenient .place, such as the basement of the building. On each floor of the building a series of: pairs of associated horizontal branch pipes 22 and23 areconnected respectively to the mainsupply.- pipe 19 and the auxiliary pipe 20.. The pipes 22 are-adaptedto deliver water to a series of vertical pipes24t leading to the sprinkler units to be hereinafter described.

Each pipe 24 is; providedwit-h a valve 25, saidvalve having a shaft 26 upon which mounted a wing 27, said wing-having an' arched shape as clearly shown in Fig.4.

Located immediately below each of the wings 27 is anozzle 28 mounted onzone of the branch pipes 23.

As willbe evident from the above construction,-when .thevalve2l is openedy-as in case of a general fire all over the building, :water will flow up through the auxiliary pipe 20 and into the branches 23. It will then pass out through tllGPIlOZZ-lGS 28 which are solocated as'to cause aijet of water to impinge at high velocity upon the-wings 27 of the valves 25. The force ofthe'water jetswill cause thewings 27 to rotate clockwise, opening the valves 25 and permitting water-from the main feed pipe 19 to How into the pipes 24 leading to the. sprinkler units-in the separate rooms of'thebui-ldinfi. In case of fixylOCiLl fire in one room, the valve 21 will be left closedand the wing127 of the valve 25 corresponding to said room will be operated manually, and in this manner only that particular room will be sprinkled.

The sprinkler units for spraying water upon the fire, and which are adapted to be located in the separate rooms of the building, will now be described. lilach of the sprinkler units comprises a hollow chamber 29 adapted to be suspended from a pipe 230 depending from the ceiling of the room where it is located. The cluunber 29 may be spherical or any other desired shape, but as herein illustrated is preferably termed in the shape of an octahedron having six corners, five of which are shown in Fig. l. The top corner 31 ot' the chamber 29 is flattened and is connected to the suspending pipe ilil. The our side corners 132 and the bottom corner :33 of the chamber are also flattened and are provided with shafts 3% which serve as hearings for propellers A top prtmellcr fill similar to the propellers is mounted to rotate about the pipe 30, said propeller being located below a bracket 37 surrounding said pipe and attached to the ceiling of the room. The bean ing shafts ll are provided at their ends with slotted leads to permit said shells to be readily manipulated with a screw driver or other suitable tool.

The propellers 35 and 36 are adapted to be actuated by water jets emerging from a series of nozzles 23?, mounted in elbows 38 screwed into the faces of the chamber 29 adjacent said propellers. The nozzles 37 are mounted parallel to the planes of the faces of the chamber and are preferably directed at a point about two-thirds out from the centre to the rim of the propellers.

In operation when any one of the valves 25 is opened, either automatically or by hand, water will flow up through the pipe 2% and downwardly through the pipe ill) into the hollow chamber 29. The chamber 29 will rapidly fill, and water will then flow out through all of the nozzles 37. The six streams of water from the nozzles 37 will impinge upon the propellers 35 and 3G,

and will, be broken up thereby and thrown from the six different corners of the hollow chamber 29 throughout all parts of the room, completely wetting the ceiling and walls of the room and soaking the burning material.

While there has been disclosed in this specification one ZEOIIH in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims,
